It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that when it was the day of Badr, the Messenger of Allah (peace and blessings be upon him) said: Whoever does such and such will have such and such (reward). The narrator says: Upon hearing this, the young men began to show eagerness, and only the elderly remained under the banners. Then, when the spoils (were gathered), these young men came to take their (appointed) reward. The elders said: You are not more deserving than us, for we were your helpers and we were under the banners. If you had retreated, you would have retreated towards us. Thus, they began to dispute among themselves. So Allah Almighty revealed these verses, from { یَسْأَلُونَک عَنِ الأَنْفَالِ } to { وَأَطِیعُوا اللَّہَ وَرَسُولَہُ إِنْ کُنْتُمْ مُؤْمِنِینَ }.

Hazrat Ibn Abbas (may Allah be pleased with them both) says in the explanation of the Quranic verse { سَیُہْزَمُ الْجَمْعُ }: This incident took place on the Day of Badr. The disbelievers said, "We are all united and victorious." Then this verse was revealed.

It is narrated from Hazrat Abu Alia regarding the interpretation of the verse of the Holy Qur'an { سَیُہْزَمُ الْجَمْعُ وَیُوَلُّونَ الدُّبُرَ }. He says: This was the day of Badr.

It is narrated from Hazrat Ibn Abbas (may Allah be pleased with both of them) regarding the verse of the Holy Qur'an { حَتَّی إِذَا فَتَحْنَا عَلَیْہِمْ بَابًا ذَا عَذَابٍ شَدِیدٍ، إِذَا ہُمْ فِیہِ مُبْلِسُونَ } that this refers to the incident of the Day of Badr.

It is narrated from Hazrat Ikrimah that on the day of Badr, the Holy Prophet (peace and blessings be upon him) was wearing armor and, expressing happiness, was saying: "The armies will be defeated, the armies will be defeated."

It is narrated from Hazrat Ali (may Allah be pleased with him) that indeed, I saw ourselves (i.e., the companions) on the day of Badr taking shelter behind the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) was the closest of all of us to the enemy.

It is narrated from Hazrat Ikrimah that the Messenger of Allah, peace and blessings be upon him, said on the day of Badr: This is Jibreel, holding the head of his horse, and upon him are the instruments of war.

It is narrated from Hazrat Umair bin Ishaq that the Messenger of Allah, peace and blessings be upon him, said: Mark (your animals), for the angels have also marked. The narrator says that on that day, wool was used for the first time.

It is narrated from Hazrat Ali (may Allah be pleased with him) that on the day of Badr, the distinguishing mark of the companions of the Messenger (peace and blessings be upon him) was white wool.

Hazrat Amir narrates that when it was the day of Badr, the Muslims began to say: "Kharz bin Jabir is helping the polytheists." This was hard on the Muslims. Upon this, this verse was revealed: { بَلَی إِنْ تَصْبِرُوا وَتَتَّقُوا وَیَأْتُوکُمْ مِنْ فَوْرِہِمْ ہَذَا، یُمْدِدْکُمْ رَبُّکُمْ بِخَمْسَۃِ آلاَفٍ مِنَ الْمَلاَئِکَۃِ مُسَوِّمِینَ }. Allah Almighty said: "If Kharz helps the polytheists, then I will help you through these angels." Then Kharz did not help the polytheists.
